        Site Description and Birding Information: This important site is now part of the newly created parc national de Plaisance or Plaisance Provincial Park. In French, it is called parc national de Plaisance. This new park extends 22.5 km from Thurso, through the Presqu'îles, to as far east as Île à Roussin. The area is being slowly developed as a park. One of the main features will be a bicycle path from the present site through to the Presqu'îles. The plan presently calls for a visitor's centre to be built at the Thurso end, near where we are now parked.
         At present the old trail to the marsh is still walkable, but soon to be replaced by a pay-per-view bike path. It is about a kilometre to the marsh through deciduous woodland along the Ottawa River (watch for migrant landbirds in migration). There is a small mound along the trail at the marsh which provides a bit of elevation for viewing. A side trail from it leads to a tower. The old viewing platform, that had fallen into ruin, has been replaced by a new tower. The Thurso Marsh itself (a.k.a. Marais Perras, Marais de Thruso or Baie Perras) is designated a protected area within the park and aside from the trails, should be left untrodden.
         Breeding birds include Marsh Wren, Pied-billed Grebe, Common Moorhen, American Coot, Virginia Rail and the rarer Least Bittern. Other birds seen in summer include Black Tern and Black-crowned Night Heron. King Rail has been reported from this site. A Great Gray Owl invader stopped here Jan. 31, 2005.
